**Your brain is full. Chrono takes the load off.** You don't need another to-do list. You need a system โ€” one place where your notes, daily routines, and long-term goals work together instead of living in separate apps you forget to open. Chrono is a productivity app built by someone who kept forgetting things, losing notes, and ignoring reminders. It's designed around one idea: if the tool isn't fast and frictionless, you won't use it. **NOTES THAT ACTUALLY WORK** Capture thoughts instantly. Tag them with one tap. Find them later without scrolling through chaos. No folders, no nested hierarchies โ€” just fast, clean note-taking that stays out of your way. **ROUTINES THAT STICK** Morning exercises. Supplements. Language practice. Set it once, and Chrono reminds you โ€” not just once, but repeatedly until you actually do it. Missed the 9 AM reminder? Get another at 9:30. And 10:00. Your routine doesn't care about your excuses, and neither does Chrono. **GOALS WITH SESSIONS** Reading. Studying. Deep work. These aren't tasks you check off โ€” they're activities you build over time. Set a session length, get a notification when it ends, and decide: one more round, or done for today? No more forgotten timers running for 14 hours. **AI ASSISTANT โ€” YOUR NOTES AS CONTEXT** Connect your own API key and let AI work with your actual notes. Summarize, translate, rewrite, or brainstorm โ€” with your own data as context. Your notes become a knowledge base, not just a pile of text. **100% OFFLINE. 100% PRIVATE.** Everything is stored on your device. No cloud sync, no account required, no data harvesting. Your thoughts stay yours. **WHY CHRONO?** - Not a planner. Not a to-do app. A productivity system. - Built for speed: open โ†’ write โ†’ done. - Smart recurring reminders that won't let you slip. - Session-based goal tracking for long-term activities. - AI that actually knows your context. - Offline-first. No sign-up. No cloud. Stop planning to be productive. Start being productive. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Deforget is a diary that remembers for you. Write about your day the way you'd tell a friend. On-device intelligence quietly picks out the things you'd hate to forget - commitments, plans, decisions, open questions, and the people they involve - and turns them into something useful: โ€ข Promises become reminders in Apple Reminders, right on time โ€ข Plans land in your calendar - and meeting notes attach themselves to their meeting โ€ข People get pages: the Index gathers everything you've ever written about anyone โ€ข Decisions and open questions stay findable, months later No tags. No forms. No filing. You just write. PRIVATE BY DESIGN Everything happens on your device, powered by Apple Intelligence. Your words are never sent anywhere - Deforget runs no servers and collects nothing. Sync happens through your personal iCloud, invisible to everyone but you. THE DIARY IS FREE FOREVER Writing, reading, syncing, and export are never locked. The intelligence - extraction, the Index, automatic reminders and events - is free for your first 7 days, then available with Deforget Pro: monthly, yearly, or a one-time lifetime purchase. Deforget requires an Apple Intelligence-capable device (iPhone 15 Pro or newer, M-series iPad, M-series Mac). With Apple Intelligence switched off, Deforget is still a beautiful, private, free diary. The intelligence understands English today. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
